-====== Backing Up Your Compact Flash Using SSH ======
-See also: [[computing:storage:disk_images|Working with Disk Images]]
-This information was taken from the IPCop firewall/router documentation.
-You may want to save the entire compact flash image as a .img file for easy restoration in case of an emergency.
-Make sure SSH (server) is enabled on the machine containing the flash memory card.  On IPCop, you use the web interface to enable SSH.  With IPCop, you also need to open the firewall port 222 if you need access from the Red (Internet) interface.
-To back up an IPCop firewall/router from a Unix or Linux machine or Cygwin on a Windows machine issue:
-<file>
-ssh -p 222  root@ip.of.ser.ver "dd if=/dev/harddisk" | gzip > backup.img.gz
-</file>
-For other than IPCop, you can omit the '-p 222' because SSH is normally on port 22.
-Change the IP address to your own IP or DNS name
-You must adjust the '/dev/harddisk' to meet your needs.
-CF cards are often /dev/hda or /dev/hdb.
-/dev/sda (first SCSI disk) is common for USB flash drives.
-If the system you are backing up does not have the gzip utility, use this
-<file>
-ssh -p 222  root@ip.of.ser.ver "dd if=/dev/harddisk" > backup.img
-</file>
-Here is another example backing up a Sonora Advanced Router where the CF card is /dev/hdc:
-<file>
-ssh root@ip.of.rou.ter "dd if=/dev/hdc" | gzip > backup.img.gz
-</file>
-This command utilizes ssh's ability to run commands submitted at the end of the command line.  In this case the command sequence uses the dd command to copy the entire physical compact flash device and then put the output into a file on your local computer.
